2 CLC/TS : Foreword This Technical Specification was prepared by Working Group 25 of SC 9XB, Electromechanical material on board rolling stock, of Technical Committee CENELEC TC 9X, Electrical and electronic applications for railways. It was circulated for voting in accordance with the Internal Regulations, Part 2, Subclause and was accepted as a CENELEC Technical Specification on Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent rights. The following date is proposed: latest date by which the existence of the CLC/TS has to be announced at national level (doa) The CLC/TS series Railway applications Mounted parts of the traction transformer and cooling system consists of four different parts: Part 1: HV bushing for traction transformers; Part 2: Pump for insulating liquid for traction transformers and reactors; Part 3: Water pump for traction converters; Part 4: Gas and liquid actuated (Buchholz) relay for liquid immersed transformers and reactors with conservator for rail vehicles. The CLC/TS series shall be read in conjunction with CLC/TS ) Railway applications - Generic system architectures for onboard electric auxiliary power systems. This standardization project was derived from the EU-funded Research project MODTRAIN (MODPOWER). It is part of a series of standards, referring to each other. The hierarchy of the standards is intended to be as follows: 1) Under development.

6 CLC/TS : Scope This Technical Specification covers requirements for centrifugal and peripheral electric pumps which generate the circulation of cooling liquid in converters of rail vehicles and their associated cooling system. The pumps covered in this Technical Specification are rotodynamic pumps driven by canned motors or magnetically coupled motors. CLC/TS gives consideration to both technical and normative requirements of the railway environment and restricts the variety provided by industry-wide standards for pumps (for example EN , EN 733 and EN ISO 9906). It determines requirements and tests enabling the interchangeability especially regarding electrical, mechanical and hydraulic interfaces. Furthermore, service conditions are described. 2 Normative references The following referenced documents are indispensable for the application of this document.
